Specification of Letters Patent.

Patented July 24, 1906.

Application filed May 12, 1906. Serial No. 316.452.

T0 aZZ whom it may concern.-

Be it known that I, JOHN THoMAs BRENT, 2d, a citizen of the UnitedStates of America, residing at Cold Spring, in the county of Putnam andState of New York, have invented a new and useful IVeight; and I dohereby declare that the following is a full, clear, and exactdescription of the same.

This invention relates to weights, especially sash-weights or otherforms of sectional weights.

The objects of my improvement are to provide a novel form of weightuseful alone or as a unit for sectional Weights, which unit is quicklyand cheaply made and finished, is very strong, and may be readily andfirmly engaged with and removed from another unit to produce asash-weight of any desired weight and which is exceedingly heavy andstrong for a given weight.

Referring to the accompanying drawings, Figure 1 is a perspective viewof the new form of weight, showing especially the form of the rib used.Fig. 2 is a perspective view of said weight, showing especially thegrooved end. Fig. 3 is a crosswise longitudinal section through a weightcomposed of a succes sion of the new units. Fig. 4 is a widthwisesection of the engaging ends of successive units, showing the relationof ribs and stops; and Fig. 5 is a perspective view showing successiveunits partly slid together.

The new weight or weight unit made according to this invention consistsof a block or body 1, preferably rectangular in shape and having one end2 inwardly curved or recessed widthwise of the unit, as shown in thedrawings, and provided at the end referred to with a rib having anoutwardlyextending web 3 widthwise of the rib and disposed at thecentral line of the unit. At its outer extremity the rib has one or moreoverhanging parts, such as overhanging flanges or side edges 4 and 5.Preferably, as shown, the overhanging flanges or side edges 4 and 5 andthe outer or extreme face 6 of the rib are curved in the same directionas and parallel with the curved or recessed end 2 of the block orv body.Preferably, also, the curves at 2 and 6 are symmetrical, though this isnot always necessary.

The length and outward projection of the l rib 3 of a unit may be anydesired. I prefer, l

however, that the length of said rib shall be, as shown in the drawings,equal to the width 5 of the block or body 1, or nearly so, in order thatsaid rib shall have maximum strength and the overhanging side edges orflanges 4 and 5 shall have maximum gripping or engaging surface orsurfaces. It will be seen also that I provide the web 3 of the rib witha suspension-opening 7, preferably, as shown in the drawings, midway ofthe length of the web, and underneath both flanges or over hanging sideedges or flanges 4 and; 5. At one end the rib 3 is diagonally cut awayor beveled, as shown at 8, without materially decreasing the length ofthe flanges, thebeveled part thus provided acting as a stop member whenengaged with another unit, as hereinafter described.

The block 1 is also provided with an end 9, outwardly curved or swelledwidthwise. of the unit, as shown in the drawings, and preferablyparallel with the curve of the end 2. Said end 9 is also formed orprovided with means to engage an end rib such as that described of anengaged weight or unit, and in the drawings I haveshown a groove 10widthwise of the end of the weight 9 and enlarged at its top and bottomto provide the inwardly-extending jaws or flanges 11 and 12 and theenlargements 13 at top and bottom of said groove. The general outlineand shape of the groove is T-shaped and corresponds to the generaloutline and shape of the T-shaped rib (provided with flanges) alreadydescribed, and said groove extends the entire width, or nearly so, ofthe end 9 of the block or unit, and in the instance illustrated one endof the groove is obstructed by a beveled part 15, constituting a stop.The other end of the groove is unobstructed or has a curved wall 14.

It will be seen that the unit shown in Figs. 1 and 2 may be used aloneas sash-weight or for other purpose. In that event an end of thesuspending-rope may be passed through the opening 7 (of a web 3) andtied, thus suspending the weight in place. If two or more of such unitsare to be used as the weight, successive units may "be slid together, as

Too

shown in Fig. 5, the rib of one unit 1 engaging the end groove of theadjacent unit 1 and the flanges 4 5 of the rib fitting the 10 5enlargements 13 of the groove and slidably bearing upon the flanges orjaws 11 and 12, as shown in Fig. 3. When two of the illustrated unitsare fully engaged, the stop 15 and the bevel 8 are squarely together,the function of the stop being to limit the sliding engagement in onedirection of successive units'and the'stiffening of the weight composedthereof. The successive units or weights are thus slidably fitted end toend, and the rib of one unit grippingly engages and interfits with thegroove of the adjacent unit. It will be seen, therefore, that the unitmay be employed alone or as a component of a sectional weight andin thelatter event may be an intermediate unit or section or an end unit orsection.

,It will also be seen that special suspending units are not necessarywith my construction and that the'sashes of an entire building, as wellthose utilizing single units as those utilizingseveral units, may beequipped with my new weight or unit.

' Asectional weight comprising a succession of my new units slidablyengaging, as described and shown, is exceedingly heavy for its length,of great strength, owing to the fact that any jars or shocks, due toraising and falling in the sash-casing, are transmitted to somewhatvclosely-fitting parts and against the full breadth of the ends of thesuccessive blocks and against ribs and flanges which are as wide as theblocks, and there are no small or fragile partssuch as smallprojections, hooks, or thin suspension-piecesto be broken away by endshocks or twisting strains.

Units such as shown in Figs. 1 and 2 are exceedingly simple to cast,requiring but one operation and a core being unnecessary and may befinished sufficiently without putting in a rattler or tumbling-machine,the use of which results in breaking projecting or small parts of units.

In the drawings I have shown units substantially square incross-section, which form gives maximum weight and strength but thecross-sectional shape of the weight sive units slidably-engaged end toend, one of said units having a curved end rib having an overhangingpart and extending centrally widthwise of the unit, and the other ofsaid units provided with a curved end groove into and extendingcentrally widthwise of the unit and conforming to, engaging andinterfitting the rib aforesaid, the successive units provided withdirectly-cooperating means for limiting the extent of'sliding engagementof the units.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
